This game works with: Basilisk II,

A great game based on arcade game called 'Star Castle'. You play a ship attempting to assault a shielded fortress in the center of the screen. This is made difficult by the fact that every time you completely destroy the outermost spinning ring of shields, a new ring is created in the center and the remaining two rings advance outward. The only way to win, therefore, is to time a shot such that it passes through the damaged parts of the shield and gets to the center. I hope that's understandable... - Mephisto

The sequel to Cyclone.

Answers to Frequently Asked Questions

Q - I registered the original Cyclone. My old serial number doesn't work with Cyclone II. Do I have to pay again?
A - Registered users of the original Cyclone (up to version 1.2.1) may upgrade to Cyclone II for only $4.95. The shareware fee for the first Cyclone was only $10, and the normal fee for Cyclone II is $14.95. So with this $4.95 upgrade, you will be paying a total of $14.95 to own Cyclone II. Your old serial number will not work with Cyclone II, so to remove the shareware notices and personalize your copy of the program, you must register Cyclone II using this upgrade payment option. Press the Order button on the Registration screen to order your new serial number.

Q - Will there be a version of Cyclone II that takes advantage of larger monitors?
A - No. If it did expand to fill the whole monitor, we would have to expand the sprites and game space appropriately, just as we shrink the sprites and space to fit on the smaller 512x384 screen. The game is designed for a specific play area - changing the play area would change the game.

Q - Are there any cheat keys for Cyclone II?
A - Yes, there are several.

Q - Why are the default keys so useless?
A - Well, what's useful depends on what keyboard you have. We use extended keyboards, which have the command, option and control keys duplicated on the right side of the main key island. So we use the 'Z' key to rotate left with the left middle finger, the 'X' key to rotate right with the left forefinger, the right command key to thrust with the right forefinger, and the right option key to fire with the right middle finger. This setup is very similar to the layout of the buttons on the original Star Castle game.

Q - Pretty-please tell me what the cheat keys are!?!
A - OK, fine. But if you cheat, your score will not be saved. Here's how to cheat:
While playing the game, press and hold the mouse button while pressing one of the following key combinations.
Press the 'C' key to toggle Collision Detection on and off for your ship. While Collision Detection is off,
enemy weapons will pass through you, but you can still pick up yummies.
Press the 'I' key to toggle Infinite Ships on and off. When Infinite Ships is on, your remaining number of
ships never decreases.
Press the 'L' key to immediately increment the Level number.
Press the 'return' key to immediately cause a Yummy Shower.
Press and hold the 'shift' key, then press the 'D' key to instantly destroy the enemy base.
Press and hold the 'B' key, then press the 'M' key to play the Mine Challenge level when the current level
is over.
Press and hold the 'B' key, then press the 'C' key to play the Castle Challenge level when the current level
is over.

C2 is hardly a sequel, more like an Enhanced rerelease of Cyclone, and C2 is 68K+PowerPC (FAT) whereas C1 is 68k alone. How's this for an enhancement: C2 main title screen offers a Volume Knob that can "go to eleven" (T.I.S.T.)

This game (the Cinematronics arcade) became the inspiration for Atari to develop "Yars Revenge", it is a very old game - it used a Vector CRT in competition with Atari Asteroids, and Star Castle gave Color to the shield rings by Tinting the CRT Glass,
a transparent overlay.

The actual reason it's difficult is that if you puncture through to the center, the cannon shoots giant plasma... things... at you.

It's a clone of Star Castle, the old Cinematronics arcade game. I remember playing it when I was barely tall enough to see the screen! I miss those arcades. Sad

This one seems to run fine in Basilisk II with Mac OS 7.
